JP PSO2 version: Episode 2 news

Release Date: Summer 2013, no date as of now yet (waiting for the broadcast to announce the info if they do)
New Class: Braver/Vanguard is a default class and not one that you have to unlock,
New Weapons: Katanas and Bows.
New Race: Dewmans from Phantasy Star Portable 2 Infinity.
New Planets: None confirmed or had been told by SoJP yet but through data-mining and a trailer it is suggested another 3 new planets are coming out with one having a beach-like area as shown in an early trailer.

Everyone is going to love this news: When Episode 2 goes live, everyone will be getting a new character slot as a compassion to having a new race and new default class in the game.

New Darker type of Enemies: They are bird-like enemies, the first shown was a hawk-like darker in the new beach area.
Returning boss: The all classic De Rol Le snake/worm boss is back as a serpent now in the new planet.
New Planet: One new planet was just confirmed and showcased with the new enemies.
Weapons: Simply badass enough for you to go braver because of the mix of range + melee style.
Another new weapon is shown: Shield-n-Sword

Will post more info a I gather some more tonight and this morning and will try to get a picture of the new monsters.

Oh biggest news for everyone because it was just announced: PSO2 Episode 2 goes live on July 17th (16th for US/EU players)

LoL no way I am going to play the English version now unless if it is up-to-date with the JP version.

Edit: Forgot to mention, when Episode 2 comes out, your sub-class will now gain a portion of the exp you receive now.

December
- New quest for 12 players
- New system for item customization

By new field, they mean planet. So one new planet during launch, another in September, and one more in December.

Edit: lol I forgot to mention something again: When Episode 2 goes live, everyone gets a my mini room for free. It's basically a small version of the My Room.

Double Edit: LoL god I suck at remembering everything: New enemy mechanic is introduce with the new planet-----A Day-n-Night time effect: Areas will now go day and night (not sure whether in-game or according to real-life timing) and will affect enemy behaviors, strength, and characteristics.
